  • Patent number: 5023597
    Abstract: A detection apparatus for monitoring specified safety eyewear being worn by persons who are either passing into or are located in the designated area which requires that a person in the area be wearing the specified safety eyewear. The detection apparatus includes an infrared reflector which is located on the specified eyewear, an infrared transmitter for transmitting a beam of infrared radiation towards the person, an infrared receiver which receives reflected radiation from the infrared reflector on the safety eyewear being worn by the person and an alarm which is normally inactive and which remains inactive as long as infrared radiation from the transmitter is reflected back to the infrared receiver from the reflector. The alarm is activated when infrared radiation is transmitted to the person and not reflected to the receiver due to the absence of specified safety eyewear which contains the appropriate infrared reflector.

  • Patent number: 5000985
    Abstract: An apparatus for and method of coating an article by the use of electro-static attraction of ionized particles which are subsequently cured. The apparatus includes a first foraminous conveyor for carrying the article through a powder coating zone and a second conveyor for carrying the article through a curing zone. The surface of the article which rests on the foraminous conveyor is cleaned of particles as the article is transferred from the first foraminous conveyor to the second conveyor. The first foraminous conveyor is also cleaned of particles after the article has been transferred. After the articles have been cured to form a coating on the article, the article is put through the coating system again except that the article is supported on the conveyor so that the surface which was not coated in the first pass through the system is out of contact with the conveyor.

  • Patent number: 4998799
    Abstract: A stereoscope for viewing two stereoscopically complementary pictures which are positioned one above the other. The stereoscope includes a housing which has left and right front openings at the front of the housing and upper and lower rear openings at the back of the housing. A passageway leads from the left front opening to one of the rear openings and from the right front opening to the other rear opening. Optical elements, such as mirrors, are located within the passageways for directing a light image from one of the pictures through one of the rear openings to the left front opening and for directing a light image from the other picture through the other rear opening to the right front opening so that the observer sees the two images as superimposed and perceives the superimposed images as a single 3-dimensional picture.
